Hydrogen has a single valence electron, just like the alkali metals. Unlike them, however, hydrogen prefers to covalently bond instead of forming an ionic bond.

Are alkali metal and alkaline earht metals similar?
The alkali earth metals act in a similar but slightly less reactive way to alkali metals
What group would lithium be in on the periodic table?
They are in group one called the Alkali Metals.Those are alkali metals. They are the most reactive of all the metals, and they are in group 1 of the periodic table, all the way to the left.
Why is hydrogen not part of the alkali metal or halogen chemical family?
Hydrogen is really in a category by itself; it isn't normally considered an alkali metal. Some periodic tables put it at the top center of the chart (that is, not in any of the groups) to emphasize that.
Why do alkali metals in group 1 react the same way to water and oxygen?
Alkali metals are highly reactive because they have little electronegative affinity for their own valance electrons and so donate them readily to elements and molecules with greater electronegativity, or molecules with constituent element with greater electronegativity.
Why are elements of group 1 alkali metals and group 7 halogens used as compounds and not as the free elements?
because god made it that way.

What due know the position of hydrogen in the periodic table and also write down similarities and dissimilarties with 1 group 4A AND 7A?
Position of hydrogen in periodic tablePosition of an element in periodic table depends upon its electronic configuration and properties. Hydrogen resembles the elements of group I-A, IV-A and VII-A in some respects. Properties of hydrogen do not completely match any one of the above-mentioned groups. That is why position of hydrogen is still undecided.Resemblance Of Hydrogen With Alkali Metals(Group I-A)1) Like alkali metals hydrogen has one electron in its valence shell.ExplanationH (Z=1): K1Li (Z=3): K2, L1Na (Z=11): K2, L8, M1(2) Both require just one electron to complete their valence shells.3) Both hydrogen an alkali metals are good reducing agents.4) Like alkali metals hydrogen can also form halides.Explanation: Hydrogen:HCl, HI.I-A:NaCl, KBr.5) Halides of alkali metals and hydrogen ionized in similar way in aqueous solution.Explanation:HCl (aq) è H+(aq) + Cl-(aq)NaCl(aq) è Na+(aq) + Cl-(aq)6) Like alkali metals hydrogen can also form compounds with non-metals.Explanation:I-A:Na2SHydrogen:H2S7) Both lose electron to form positive ions. E.g. H+, Na+8) Alkali metals and hydrogen belongs to s block.DIFFERENCES :-1) Hydrogen is a non-metal where as elements of I-A are metals.2) Hydrogen can form both covalent and ionic compounds. But alkali metals only form ionic compounds.3) Hydrogen can gain an electron to form H- ion.4) Hydrogen is a gas at room temperature but alkali metals are solids.5) Unlike Na+ or K+ hydrogen ion (H+) is unstable in water.Explanation:H+ + H2O è H3O+6) Alkali metals do not occur freely in nature due to their high reactivity but hydrogen does occur.7) Hydrogen occurs in diatomic state (H2).8) I.P. of hydrogen is very high as compared to alkali metals.Resemblance of Hydrogen with Carbon Family (IV-A)1) Valance shell of hydrogen is half-filled like the elements of group IV-A.Explanation:H (Z=1) : Capacity of K-Shell =2 , no. of electrons = 1 , % = 50%C(z=6) : Capacity of L-Shell = 8 , no. of electrons = 4 , % = 50%2) I.P. and E.A. of hydrogen and carbon are comparable.3) E.N. of H and Carbon family are almost similar. [H = 2.1, C = 2.5 , Si= 2.4]4) Both show reducing effects.Explanation:CuO + H2 è Cu + H2OSnO2 + C è Sn + CO25) Both combine with other elements through covalent bonding.ExplanationDIFFERENCES1) Carbon is tetravalent but Hydrogen is a mono-valent.2) Hydrogen is a gas at room temperature but elements of group IV-A are solids.3) Boiling and melting points of hydrogen is very less than that of the elements of group IV-A.Resemblance Of Hydrogen With Halogens1) Both Hydrogen and Halogens require one electron to complete their valence shell.2) Both hydrogen and Halogens are non-metals(Except iodine which has partial metallic character).3) Both hydrogen and Halogens acts as negative ions when combined with metals. 4) Their molecules are diatomic.5) Like Halogens, hydrogen can also form both ionic and covalent bond.ExplanationHydrogen:NaH (ionic),CH4 (Covalent)Halogens:NaCl (ionic), HCl6) Both H and Halogens form compound with metals and non-metals.ExplanationHydrogen :H2S [S=non-metal]Halogens : HCl [H = non-metal]DIFFERENCES1) Hydrogen has one electron in valence shell while Halogens has seven electrons.2) Electronic configuration of H = 1S1,Valence shell electronic configuration of Halogens = nS2, nS53) Unlike X- ion, H- ion is unstable in water and reacts in the following manner.ExplanationH- + H2O èH2+ OH-UNIQUE ATOMIC STRUCTURE OF HYDROGEN:Hydrogen is the only element which has no neutron in its nucleus.ConclusionDue to above reasons it is clear that hydrogen cannot be placed in any one of the above mentioned groups.
What are other elements in the hygrogen family?
Hydrogen isn't really in a "family". It's a little bit like the alkali metals and a little bit like the halogens, but it's not exactly either of those things.Personally, I consider the hydrogen "family" to be: hydrogen, full stop.It's possible the author of your textbook disagrees, in which case he or she is wrong, but your teacher may not see it that way, so you probably should try reading your textbook for the answer given there before relying on my response.
What gas is produced when calcium metal is dropped in water?
HYdrogen. The Group (II) Alkaline Earth elements, of which calcium is one, react in a similar way the Group (I) Alkali metals, but less vigorously. So like sodium and water produces sodium hydroxide and hydrogen . # Then calcium and water produce calcium hydroxide and hydrogen. Here is the reaction eq'n. Ca(s) + 2H2O(l) = Ca(OH)2(aq) + H2(g) .
Is Ibuprofen an acid or an alkali?
Actually, it's both. It's got a basic hydroxyl group sticking out there, and an acidic hydrogen on that Nitrogen atom. But not very strong one way or the other...
Why do alkali metals in group 1 react the same way to water and oxygen?
Alkali metals are highly reactive because they have little electronegative affinity for their own valance electrons and so donate them readily to elements and molecules with greater electronegativity, or molecules with constituent element with greater electronegativity.
Why are elements of group 1 alkali metals and group 7 halogens used as compounds and not as the free elements?
because god made it that way.
Most metals are NOT what?
None are more metallic. Metallic is a way of describing a metal in general.
Is. Hydrogen a metal or non metal?
The answer is both, keep in mind that hydrogen is an exception. This is science and here's the scientific answer.Hydrogen can be pressed into a liquid metal when under extreme atmospheric pressures like those on planets of Saturn and Jupiter (their pressure is 300 million + times that of Earth.)Under typical conditions however, hydrogen is a nonmetallic gas.
